I EUGENE A. DE MAY, OF RICHMOND, TEXAS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 364,494, dated June '7,1887.

Application filed March 17, 1887. Serial No. 231,281.

To all whom it may concern:

Be it known that I, EUGENE A. DE MAY, of Richmond, in the county of FortBend and State of Texas, have invented a new and Improved Car-Coupling,of which the following is a specification, reference being had to theannexed drawings, forn'iing a part thereof, in which- Figure 1 is aperspective View showing the application of my improved car-coupling toa car, and Fig. 2 is a horizontal section taken on line 00 x in Fig. 1.

Similar letters of reference indicate corresponding parts in both views.

The object of my invention is to provide a simple and effective devicefor automatically coupling cars of varying heights, and also to providedevices for uncoupling the cars without the necessity of going betweenthem.

My invention consists in a springpresscd hook attached to or formed upona rock-shaft extending to the top of the car, and provided with ahand-wheel, by which it may be turned.

It also consists in the combination, with the hook,of a rod connectedthereto and extending to the side of the car, for uncoupling the carfrom the ground.

In the draw-bar A, carried by the car A, and in the arm B, projectingfrom the top of the car, is j ournaled a rock-shaft, O, carrying at itslower end a hook, D, having a rounded notch, a, andar'ounded nib, b.Surrounding the shaft 0 is a spiral-spring, E, which rests upon thedraw-bar A and presses upward against a nut, F, on the shaft 0. Theupper end of the shaft 0 is provided with a hand-wheel, G, by means ofwhich it may be turned from the top of the car.

The extremity of the hook D is beveled from the top downward, tofacilitate its engagement with a similar hook carried by a higher car.An ear, 0, projects from the back of the hook D, which is pivoted to theend of a rod, 11, extending through aguide, e, at the end of the (Nomodel.)

The notch a and nib b of the hook are of WVhen it is desired to uncouplcthe cars from the top of the cars, the hooks D are thrown back byturning the hand-wheel G, and when it is desired to uncouple the carsfrom the ground the hooks D are drawn backward by means of the rod d.

It is obvious that my improved coupler can be applied to the ordinarydraw-bar, thereby saving the expense and delay of making and fitting anew draw-bar.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In a car-coupling, the combination of theshaft (3, provided with the nut F and carrying the hook D, the spring E,resting upon the draw-bar A and pressing against the under surface ofthe nut F, and the springaetuated rod d, substantially as described.

2. In a car-coupling, the combination of the shaft 0, the hook D,carried thereby, and provided with a beveled end, the spring E, the nutF, the hand-wheel G, the rod (Z, the guide 6, and the spring g, placedon the rod between the guide 6 and hook D, substantially as de' scribed.

EUGENE A. DE MAY.
